I recently purchased Pico USB data logger DrDAQ and start a tets with Mac. When I installed PicoScope-6.11.13.2.pkg on my MacBook Pro along with MonoFramework MDK-5.0.1.1., The device did not work correctly. Only demo mode was available.I then tried to install the MonoFramework version MDK-5.2.0 and the situation got even worse because neither Demo mode became available. However, after deleting the MDK-5.2.0 version and reinstalling the MDK-5.0.1.1 version, the device worked perfectly well, both in DEMO mode and acquisition mode. I would like to understand what happened.
